HUMIDIFIER AND .lTIR-MOISTENING APPARATUfi.

Application filed July 2,

To all whom it may concern:

Be it known that T, STUART W. CRA'MER, a

citizen of the United States, residing at.

Charlotte, in ,the county of Mecklenburg and $tate of North Carolina, have invented certain new and useful Improvements in Humidifiers and Air-Moistening Apparatus; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for moistening the air in rooms or factories, and has for its object to provide an apparatus which will not only keep the air constantly supplied with any preferred amount of moisture, and diffuse such moisture throughout the room, but also an apparatus that will perform the additional function of cleansing the air.

The invention consists in certain improvements in construction as will be fully disclosed in the following specification and claims. I

In all departments of textile factories, but particularly card rooms and the like, the atmosphere is heavily charged with lint, dust and other impurities. An efficient system of humidifiers should provide not only for the proper humidification of the air but for the proper cleansing of the air, for it is only by such an apparatus that the air can be cleansed in a commercial practical way, other than by completely removing the foul and substituting new and fresh air therefor. The latter method would. obviously be the preferred method theoretically, but practically it would be too expensive to be commercial; it is possible, however, to so combine the two systems, that fresh-air can be brought in from the outside and passed through ventilating types of humidifiers in suflicient quantity to maintain a healthy standard, which is ordinarily considered to be such that it does not contain over nine parts of'carbonic acid gas in ten thousand parts of-air; and the remainder of the at mosphere in the room can be cleansed if it be passed through inside humidifiers often enough for the dust, lint and other impurities o be condensed and separated by the water. There are several different types of apparatus which accomplish this result to a greater or less degree. In all of them there collects on the inside of the casings Specification of Letters Elatent.

layer after layer of these impurities which not only impede the draft, but also turnlsh brcedlng ground for bacteria. These bacof disease and thrown 013 from the operatives by respiration, perspiration, or othen wise, are carried about in suspension in the atmosphere, and deposited on the layers of lint and other impurities that line the cas ings of the humidifiers, where they multiply in great number, to be again picked up and disseminated throughout the rooms by the air issuing from the humidifiers. The superiori'ty of the spray type of humidifier with its draft of air through the casing ias never been questioned as compared to any other system as regards eiliciency, economy in the use of power, and distribution; the principal objection to it, in the minds of many thoughtful manufacturers has been that it is unsanitary for the reasons above given. In other patents that have been sued to me and some applications for patents that are still pending, T have endeavored to provide an apparatus that would lessen this objection and to devise a construction that would permit of the different parts being readily accessible. I have aland cones can be cleaned. The present improvement contemplates a still further development of construction by which the casings can be readily detached and re the mill yard and scrubbed and washed pcrfectly clean. Tt is not enough to say that any type of humidifier can be taken down by breaking its pipe connections and loosenmechanical operations; the employees will not take the trouble to do these things :7 has been proven by many years experience.

The purpose of my improvement is therefore to provide a construction so exceedingly simple and so readily detachable that it is practically no more trouble to remove a casing to be washed, than it would be to pick up a Water pail or perform some other comparatively simple'manual operation.

In the accompanying drawings, which form part of this specification :-F igure 1 represents a vertical section partly in elevation, of my improved double casing type of humidifier in its normal or working position. Fig. 2 a like view, showing the casings raised for cleaning the basin. Fi 3 a like teria which are in many cases the products.

ready provided means by which the basin mg some bolts and performing a few other 1 moved, whereby they can be taken out in L? laterally to the left and the inner and outer casings 1 and 12 ing .14 removed laterally to the right. It is obvious that this operation is both simple and expeditious, all three casin s being simply lifted together enough ior their lower ends to clear the lower part of the apparatus, the lower ends being then lifted outward and the upper ends lowered unt1l they clear the spray head 2.

In Fig. 5, the same numbers designate corresponding parts in the preceding figures. 22 indicates a centering and positioning spider for positioning the spray casing l with reference to the spray head 2. 23 is a thumb set screw for supporting the spider in elevated position, with or without the y casing 1 attached thereto. l In Figs. 6, 7, and. 8 operations analogous to those in Figs. 2, 3 and 4 are illustrated and the same numerals indicate similar parts. i

In the several figures the parts of the construction shown which are not included in view, showing the upper and supplemental casing lowered for access to the nozzle, and also in position for removing it and the double casings from the apparatus. Fig. 1 a like View, but at a right angle to the position shown in Fig. 1,showing the casings being removed at one side, and the cone removed at the opposite side. Fig. 5 represents a vertical section partly in elevation, of r my improved type of single easing spray humidifier in its working position. Fig. 6 a like view, showing the casing raised for the purpose of cleaning the basin. Fig. 7 a. like view, showing the centering spider raised to permit ready access to the nozzle, and Fig. 8 a like view, but at a right angle to the position shown in Fig. 5, showing the casing being removed at one side, and the cone removed at the other side.

Reference being had to. the drawings and the designating characters thereon, the numeral 1 indicates the inner or spray casing, within which is the spray nozzle 2.

3 is a collecting basin and 1 is a deflecting cone.

5 is a combined stop cock and strainer for the water supply and 6 is the waste water the present invention and which are fully disclosedv in my prior patents and applications for patents are not herein described.

It is obvious that changes in details of construction and the arrangement of the waste water pipe.

11 are handles for the convenient handling without departing vention.
